Re: Ti-86, ROM 1.3: BUG with function of function!?
Not true. The 86, like every TI calculator except the 85, can use function
notation for graph equations. y1(5) gives y1 for x=5. y1(x) is just
amazingly redundant, seeing as how x is the variable that's already in y1.
I suspect that is confusing the calculator somehow. The solution? Even if
you think y1(x) should work, just forget it and use y1. No use fighting
over it when there's a way around it.
